I highly recommend David Burleigh over at H&R block (located at Golden Gate and Van Ness - easy parking nearby so you can visit in person if you like).
David worked at Apple early on, and is an entrepreneur himself, so he "gets it". Plus, he and his teammate (I forget her name) have been doing this for 15 years each, so they are extremely fast and efficient. They can easily help you with your personal filings (I REALLY wish I would have gone to them two years ago when I first started out) and they know corporate tax law inside and out and will be able to help you save money as well as the stress of trying to deal with these things on your own.
Plus, David is working closely with Xero, as he thinks that's going to be the accounting system of the future. He's a great guy, definitely worth a chat.
Let me know if you'd like an intro.
